A first embodiment of a lifting device for a frame cover comprises a pair of arms, each arm having a proximal end comprising a shank and a distal end comprising a hook configured to grasp the frame cover via a hole or other structure therein. A clamp is configured to maintain the shanks of the arms in a fixed parallel orientation during use. A second embodiment comprises a U-shaped horizontal bracket having a pair of pivot slots, and a pair of angled gripper arms pivotally connected to the U-shaped bracket at the pivot slots. Each gripper arm has a notch, hook, or other connector at a lower end thereof for facilitating grip of a frame cover. The device has a lifting point for connection to a lifting mechanism to thereby provide a lifting system for raising frame covers or other structures using the inventive lifting device.
